The sulfided sorbent was regenerated at a program-controlled temperature of between 400 and 750 °C, by using a gas mixture containing 5% oxygen, 10% steam and the remainder, nitrogen. Sorbent regeneration was considered to be complete when SO 2 concentration was less than 3 ppm in the outlet gas from the reactor.

Florida's Geologic History and Formations

Florida has unique origins. What would become the basement rocks of Florida were once part of other continents. During the early part of the Cenozoic Era, Florida was submerged under a warm, shallow, ocean which explains why our entire state has hundreds to thousands of feet of limestone beneath it! Land emerged from the ocean as sea level fell during the Oligocene Epoch.
